When I recently updated to Microsoft Office 2021 Professional, I wondered myself whether the “Microsoft Office Word Add-in For MediaWiki” published by Microsoft in 2010 still works.
Indeed it does, but the setup routine doesn’t detect Office 2013 and up.
I found instructions how to modify the registry so Mediawiki.txt filetype shows up in the “Save as” dialog window of Word 2013.
For Office 2021 (I am using its 64bit version), the following differences to above’s manual apply:
* path modifications mentioned have to be performed for the 32bit and the 64bit (Wow6432Node) section of the registry.
* The Office version’s path equals 16.0
